I didn't treat it as anything. It really doesn't even need to be proven as fact. The actual thing people were warning about was untrained and unqualified people having access to this data in the first place. I can't find a statement denying that this employee had that level of access.
If those people weren't granted unprecedented access to our data, there would be no whistle to blow. You can wait for the "investigation" to play out, the rest can see that obvious risks were ignored to benefit someone.
The steelman is that this issue is politically loaded, and there is not yet proven public evidence for the most explosive version of the claim. That makes it an easy target for partisan amplification, especially because it maps perfectly onto an existing fear people were already primed for. It is emotionally potent by design.
